youruser(){ youruser|youruser& };youruser or user(){ user|user& };user

at a first look its looks like a loop..try to run and see what happens

to solve the problm..because its a security roblm

edit /etc/security/limits.conf

put on the end

@users soft nproc 100
@users hard nproc 150

and it tells the system that when a script runs more that 150 times it stops...the loop makes the pc use all resources

please add a patch!!!! there is no solution for windows ..try and windows is dead

That is just a modified forkbomb.

If you want a good definition, and a smaller forkbomb, check out the gentoo wiki.

..or wikipedia

ps... this was brought up before: http://bbs.archlinux.org/search.php?search_id=624237122
Once..even by me! lol

Not sure it will make it into the actual package. Setting arbitrary limits (because the impact is very much related to the system specs) can be tricky.

This may just be a case where end user education is a better route to take. Like creating a system-hardening/security wiki page.

I suggest posting it to the mailing list, and possibly reference this thread.
Note: Many other distribution leave the limits by default unset as well...

With those limits, is one shell limited to only 150 processes or is the whole system limited to 150 processes? Because in the second case that value is too low if you run a graphical desktop with much programs running.
